Constant NO_HANDLE

pub const NO_HANDLE: HandleId;
Expand description

Sentinel “no handle” — distinct from any valid handle (which start at 1).

Mirrors core.ts:57 NO_HANDLE = 0. Used for:

  • cache of compute nodes that haven’t fired yet.
  • prevData[i] for deps that haven’t delivered DATA yet.
  • First-run gate condition (R2.5.3).

Per the handle-protocol cleaving plane, the binding-side registry refuses to intern undefined/None (the global SENTINEL per R1.2.4 / Lock 5.A); no real handle ever collides with this.
